  1. Ford Power Promise

    ...I got the FCSP because of the 80A charging capability (future proof) and the possibility of V2H with the HIS - I later realized the HIS from SunRun was not a great idea - so many people have issue with theirs. Someday Ford might agree to let us use other V2H/V2G systems with our Lightnings...

  2. Front vs rear frequency

    ...to getting the full 9.6kW it seems to me is probably tapping into the HV battery with an external inverter (the way the Delta BID of the SunRun system does) but to get the Lightning to do that with any external inverter would require "hacking" the control in the Lightning (and maybe the FCSP...

  3. Massachusetts - Vehicle to X Program

    ...EV as long as the charge port conforms to that EV’s plug type. For example: Ford F150 Lightning vehicles have a CCS plug, and the Wallbox, Sunrun HIS, and Ara come with CCS plugs. The Tesla EV would require a NACS adaptor to charge using those chargers, but a Chevrolet Bolt EUV would be able...

  4. Massachusetts - Vehicle to X Program

    Are you saying V2H isn’t enabled? Are you sure? thought that was the point the X in V2X. Otherwise it’s just V2G.

  5. Home integration system

    Thanks! I guess I’ll have to wait for something better!

  6. Home integration system

    Well your level of expertise is above my understanding and unfortunately all these solar companies seem to be limited in the capabilities of V2H systems. Thanks for the information! I just really want to power my house when we lose power and be able to power my truck with my solar panels during...

  7. FCSP RS485 port access Success!

    Following, and likely able to do some testing. I have a FCSP but do NOT have a the SunRun inverter part, so only able to talk / test with the FCSP.

  8. Home integration system

    I believe Sunrun doesn't do it any more. I believe Ford has switched to using QMerit.

  9. Massachusetts - Vehicle to X Program

    ...and switch the 30 amp breaker on. It's not automated so there's no one to blame but me if doesn't work (and I like it that way! :) ) BTW, Sunrun and Ford need to keep best people on it, this kinda thing is a moving target so, unlike the above mentioned low budget HIS, it's never just "done".

  10. FCSP RS485 port access Success!

    Hopefully this is a better quality photo. it looks like they're in the off state. Nice! Is the developer key something that needs to be scraped off device or gotten from signing up with the vendor listed there?

  11. Massachusetts - Vehicle to X Program

    ...demo, they will own the stack, and it sounds like support is there from all the stakeholders and vendors to make this happen. He also said Sunrun was invested in this and put their best people on it.. (Likely cause they hope this will open up to the wider public in 2027?) But come 2027... Who...

  12. FCSP RS485 port access Success!

    ...board points to a switch specifically used for termination within a circuit or system, such as in RS-485 applications. In the fully wired HIS (SunRun doc) the top RS485 is wired and the SW are like this (no change): Too small to read the SW position, probably indicates an ON or OFF state?

  13. Massachusetts - Vehicle to X Program

    That's "comforting" because from my point of view the issue with HIS is no one owns the "entire stack". It's just like when you have a problem with some software, the vendor tells you to call Microsoft and Microsoft tells you to call the vendor. I wonder if they will let us keep whatever TMH...

  14. Massachusetts - Vehicle to X Program

    It was both Joey and Corey. They confirmed Sunrun is doing the install. And that it will be the FCSP with HIS. But then TMH will do a software layer over that... He also thought it would be a newer model of the FCSP. So even if you have one, it'll get replaced. They are going to be working on an...

  15. Home integration system

    As others noted, I would strongly advise against using the Sunrun HIS. I have read and seen several YouTube videos of how poorly it works. Supposedly Enphase is coming out with a vehicle to home/grid charger. But it’s been promised for quite a while now and no new news on it. Last I saw was that...

  16. Home integration system

    PS: I just read that AEE Solar is closing/closed after 45 years in business, Sunrun bought them, so not sure where you could order the HIS equipment other than from SunRun if you wanted to have your own installer...

  17. Home integration system

    The SUNRUN system uses a DELTA Bi-Directional Inverter for example, and it used to be possible to buy the equipment from AEE Solar (about $4,000 in hardware as I recall) for example, and use Qmerit or another qualify installer, but I haven;t checked lately because I decided not to try it given...

  18. Home integration system

    I've got my eye on the PointGuard system. It does look very promising. Using my solar when the grid is out is a big priority for me. @RiqRod I have not yet done anything. I'm hesitant to invest in anything in particular with so many products "coming soon". I really like Emporia products and...

  19. Massachusetts - Vehicle to X Program

    They have to have other options but I guess we will see.

  20. Massachusetts - Vehicle to X Program

    I got an email from Sunrun asking for the vehicle VIN. I cannot do the FCSP. I have tried and given up getting that on the WiFi. I hope that doesn't become a showstopper.
